The instrument design uses a single, nearly contiguous volume of organic scintillator that is internally subdivided only as necessary to create optically isolated pillars, i.e., long, narrow parallelepipeds of organic scintillator.
In Bangladesh, the 200 μg L-1 contour of As concentrations delineates what appears to be a contiguous volume of contaminated groundwater that extends from below a depth of ~10 m near the river (B1-B2) and is restricted to a depth below ~18 m inland at B5.
CT scans typically generate multiple 2D anatomical images that may form noncontiguous or contiguous 3D image volumes at a high resolution from which the difference in density between adipose vs nonadipose tissue can be quantified using tissue segmentation image analysis.
This SPM{F} was thresholded for regions of at least 15 contiguous voxels (a volume of ∼0.4 cm) that survived the threshold for local maxima of P < 0.05 (FWE-corrected across the whole brain).
Acquisition parameters were: repetition time (TR) = 1800 ms; echo time (TE) = 30 ms; flip angle (FA) = 90°; 220 volumes; 45 contiguous axial slices; anterior posterior acquisition; in-plane resolution = 3.75 × 3.75 mm; slice thickness = 4 mm; field of view (FOV) = 240 × 180 × 240 mm; total acquisition time = 6.6 min. Slice acquisition order was contiguous.
The timings and parameters used were similar to those used in previous resting-state studies (De Luca et al., 2006); 25 contiguous axial slices, 128 volumes, anterior-posterior acquisition, in-plane resolution = 2 × 2 mm, slice thickness = 6 mm, repetition time = 3000 ms, echo time = 40 ms, field of view = 260 × 260 mm, acquisition time = 6.65 min.
CTDIvol is the main radiation dose indicator in spiral CT, integrating the radiation dose for a single slice delivered both within and beyond the scanned volume, representing the average radiation dose for a single slice in the scanned volume for contiguous scans.
They were not defined using more standard voxel-wise statistical comparisons (aside from the initial conjunction analysis that involved cluster-size corrections), and there was no requirement that all the relevant voxels be contiguous in the brain volume.
Because barotrauma is probably due to the differential lung stretch of contiguous lung units, tidal volume is probably more relevant than airway pressure, but this too needs to be resolved.
